Ive noticed that a few people have changed there inen filter on their intake to either a k&n or apexi filter. Does it make a difference from the stock injen filter and did anyone have to buy any other parts to make the new filter fit like an adapter or something else. Just would like some opinions from people who have done this or just opinions in general. Thanks lv6speedmax.

 

I switched to the Apexi power intake. Apexi sells adapter that you need to mate it to Injen plumbing. I thought I noticed a return of some low end torque and a smoother sound to at WOT. That's my subjective opinion.
